IMPROVEMENT IN AUTOMATIC FANS.

Specification forming part of Letters Patent No. 13h68?, dated April 8,1873; application filed February 17, 1873.

To all whom it may concern:

Be it known that I, FREDERICK W. JoNEs, of Orangeburg Court House, inthe county of Orangeburg and State of South Carolina, have inventedcertain new and useful Improvements in Device for Keeping Flies awayfrom rIables, 85o.; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to theaccompanying drawing and to the letters of reference marked thereonwhich form a part of this specification.

rJhe nature of my invention consists in the construction and arrangementof a device for keeping off ies, as will be hereinafter' more fully setforth.

In order to enable others skilled in the art to which my inventionappert-ains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, in which-Figure 1 is a front View, and Fig. 2 is a vertical section, of myinvention.

A represents a box or case of any suitable dimensions, which is to beattached in a vertical position to a board in the ceiling, or any otherdesired location.` Within this box is a clock-work, B, run by a weight,O, and cord, a. This cord is intended to be run over suitable pulleys tothe outside of the house, or in any other position so 'as to be out ofsight.

The shaft c of the last pinion d of the clockwork extends through thefront of the box, and ison its front end provided with a crank, f, whichconnects with the inner ends of two pitmen,'D D, running in oppositedirections, the outerends of said pitmen being pivoted to levers E E.These levers are pivoted in the ends of a bar, H, attached to the frontside ofthe box, and each lever has on its lower end a brush, G. Bywinding up the clockwork B the weight O will cause thecrank f to revolveand give the brushes a reciprocating motion. As many brushes may be usedas desired by adding levers and pitmen and increasing the weight.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-- The arrangement of the crank f,pitmen D D, levers E E, and brushes Gr G with the stationary arm H,weight O, and operative mechanism, and the portable box or case A-adapted to be hung up in any desired place, as and for the purposespecified.

In testimony that I claim the foregoing as my own I attix my signaturein presence of two witnesses.

FREDERICK W. JONES.
